A Kaplan turbnine develops 2300 kW at an available head of
32 m. The speed ratio and flow ratios are respectively 2.1 and 0.62. The
diameter of the boss is 1/3 the diameter of the runner. Assuming an overall
efficiency of 88%, estimate the diameter, speed of rotation and specific speed
of the runner.
